Smart Contract Security Analysis Report
Vulnerability: Lack of Proper Access Control in updateRegistry Function
Date: 13.11.2024
Severity: Low
Description:
The updateRegistry function in the GivingThanks contract allows any user to update the registry address, which is likely a security concern as it could be exploited to disrupt the charity verification process or redirect donations to unauthorized addresses.
Mitigation:
Restrict access to this function to only the owner of the contract:
function updateRegistry(address _registry) public onlyOwner {
registry = CharityRegistry(_registry);
}
Note: This assumes the GivingThanks contract inherits from Ownable as per the import statement.
